This was also the first mass produced W-CDMA direct conversion receiver. The second one was high-integrated SiGe transceiver-IC used in PDC terminal. He developed the first SiGe PDC transceiver IC that has been used for mass-produced mobile terminals since 2001. From 2002 to 2008, he engaged in development of HW for 3G mobile terminals. Now he is charged in Corporate R&D in Mitsubishi electric.  He has authored and co-authored 25 transaction and journal papers and 47 international conference refereed papers including 3 invitations for the IEEE International Microwave Symposium, the RF-IC symposium and the Radio and Wireless Conference that are sponsored by IEEE MTT-S.
